Also note that if your work is part of a major alteration, it may have to be done in compliance with San Francisco's Residential Energy Conservation Ordinance (RECO), so develop your plans accordingly. For more information, call the DBI's Housing Inspection Services (HIS) at (415) 558-6220 for a booklet explaining these requirements.

Finally, be sure to read through the DBI's comprehensive online booklet, How to Obtain a Permit for 1 & 2 Family Dwellings, which will provide you with more details on electrical permits, including the relevant fee schedule and exactly which types of electrical jobs are exempt from permit.
